Question 1: A worker is found unresponsive at the base of a tree after a suspected fall. After confirming scene safety, the NEXT step is to:
- Immediately reposition the worker to check for injuries
- Check for responsiveness and call for emergency medical services (Correct answer)

- Place the worker in the recovery position and wait
Correct answer: Check for responsiveness and call for emergency medical services
Checking responsiveness and activating EMS are the priority actions in any suspected traumatic emergency before further assessment.
Question 2: Which type of hazard assessment is conducted continuously throughout a task, rather than only before work begins?
- Pre-job hazard analysis
- Dynamic risk assessment (Correct answer)
- Annual safety audit
- Equipment inspection checklist
Correct answer: Dynamic risk assessment
Dynamic risk assessment is the ongoing process of recognizing and responding to changing hazards as conditions evolve during work.
Question 3: Under OSHA 29 CFR 1910.269, the minimum approach distance for unqualified workers near energized lines operating at 50kV or less is:

OSHA 1910.269 establishes a 10-foot minimum approach distance for unqualified workers near lines up to 50kV.
Question 4: A crew is working in a residential neighborhood when a homeowner enters the work zone. The crew should FIRST:

- Stop all hazardous operations and direct the homeowner to a safe area outside the exclusion zone (Correct answer)
- Ask the homeowner to sign a liability waiver before speaking with them
- Hand the homeowner a hard hat and allow them to observe
Correct answer: Stop all hazardous operations and direct the homeowner to a safe area outside the exclusion zone
All hazardous operations must stop and bystanders must be escorted to a safe area to prevent struck-by incidents.
Question 5: Which element of an effective safety program is described as 'leadership visibly participating in safety activities'?

Management commitment means supervisors and owners actively demonstrate that safety is a priority through their own visible participation.
Question 6: Heat stroke in a tree care worker differs from heat exhaustion MOST significantly because the worker:
- Has profuse sweating and pale skin
- Has stopped sweating and has an elevated core body temperature above 104°F (Correct answer)
- Complains of muscle cramps and weakness
- Is mildly confused but can answer simple questions
Correct answer: Has stopped sweating and has an elevated core body temperature above 104°F
Heat stroke is a life-threatening emergency characterized by the failure of the sweating mechanism and core temperature above 104°F (40°C).
Question 7: A portable fire extinguisher should be maintained on a tree care job site primarily for:
- Cooling overheated chainsaw engines
- Extinguishing equipment fires involving chipper, trucks, or chainsaws (Correct answer)
- Providing water for first-aid wound irrigation
- Controlling smoldering wood chips in the chipper drum
Correct answer: Extinguishing equipment fires involving chipper, trucks, or chainsaws
Fuel-powered equipment used in tree care can ignite, and a fire extinguisher provides the means to suppress small equipment fires before they escalate.
